AUBURN, Alabama – Auburn defensive back T'Sharvan Bell says it's time for all his teammates to step up and turn around the Tigers' 1-4 season.

"The guys who are not all in, simply need to get gone," Bell says in this video.

Auburn is coming off a 24-7 loss to Arkansas, and now will try to win its first SEC game at Ole Miss on Saturday.

Bell is looking everybody to pull together.

"We've got certain guys you have to question their effort, and it shows on film," he said Sunday night. "You've got some guys who are kind of borderline because they're not playing as much as they'd like."

Bell was a defensive back on Auburn's 2010 national championship team. The Tigers are 9-9 since beating Oregon for the BCS title.

"We've seen what a great team looks like. You try to impress on that on the younger guys," he said. "For whatever reason, if they're not all in, or whatever the case may be, you just try to tell them, 'Just keeping pressing.' Be the best player and you're going to play. If not, you've got to sit back and wait your turn and be a team player."

Bell says the problems aren't because of a lack of effort.

"I think the guys played hard. It was just a level of execution. Too many missed tackles; too many mental errors; not being able to take the block. I think that's the glaring thing," he said.

Bell says he can tell when a player is not giving his best.

"It's body language. You can tell when a guy is borderline, maybe jogging from here to there. Little things. Coach has to keep repeating the littlest things, and they don't want to fix it as a player. Those are the guys who are borderline: 'I kind of want to be there; I kind of don't.' Right now, we're 1-4, and a lot of guys are, 'I can't wait until this is over.' We can't have that."

And: "We don't want guys to lose sight of the goal. We can't win a championship right now, but we're still very capable of winning every game on the schedule. We try to impress that on the guys. A lot of guys may lose faith because we're 1-4, but I never stop believing in the coaches and the guys fighting next to me."

Bell added, "We definitely need some good things to happen for guys to start believing… We should always be excited to step on the field, and we didn't have that Saturday."
